Brainliesttt ! -how did the us support the allied forces during the first two years of wwii? -why did the us enter wwii?

The US supported the allied forces by sending to their allies weapons, Food, ammunition, support of first aid, and cloth. The US was`t looking to get involved into the world war. Plus they were stuck in the great depression they did`t have the enough money and men for that war so they just decided to stay away. But they entered the war in December 7 of 1941 when the japan`s attacked the port of pearl harbor. Devastating and destroying their targets the japan left with a flawless victory. But the US was not going to let the japan to get away they armored up with valor and hate to enter WWII. They had their fight to with japan when they threw down both Atom bombs on Hiroshima and Nagasaki. And they helped their allies to lead them to victory to push through the gates of Berlin and they had their own vengeance on japan.
